This database includes beat annotation files for 29 long-term ECG recordings of
subjects aged 34 to 79, with congestive heart failure (NYHA classes I, II, and
III). Subjects included 8 men and 2 women; gender is not known for the
remaining 21 subjects. The original ECG recordings (not available) were
digitized at 128 samples per second, and the beat annotations were obtained by
automated analysis with manual review and correction.
